Abstract:
We present calculations of resonant Raman scattering (RRS) at the M,,, thresholds of Gd in the scattering channel 3d(10)4f(7)–>3d(9)4f(8)–>[4p(5)4f(8)4d(8)4f(9)]. We have included in the final state the interaction between the two configurations within the brackets, having one 4p and two 4d holes, respectively. The influence of the configuration interaction on the scattering spectra is shown to be important. The calculations are made within a purely ionic model including only the spectral features dispersing with the incident photon energy and do not account for the M-4 to M-5 Coster-Kronig conversion. The calculations are compared with recent experimental results on Gd metal. The agreement is excellent when choosing the excitation energy in the M-5 region. In the M-4 region the calculations agree with the measurements by assuming that the Coster-Kronig contribution is approximated in shape by the RRS spectrum measured with direct M, excitation. The implications of the results are discussed. (C) 2002 Elsevier Science B.V. All rights reserved.
